CHARLES A. V. GONZENBAGH, OF NEW YORK, N. Y.

EMBROIDERING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 252,659, dated January 24, 1E82.

Application filed June 13, 1881. (No model.)

To all whom it may concern Be it known that I, CHARLES A. V. GONZEN- BAGH, of the city, county, and State of New York, have invented certain Improvements in Embroidering-Machines, of which the following is a specification.

The object of this invention is to facilitate the operation of embroidering with beadwork, so termed; and it com prises certai n novel combinations of parts for feeding the beads to the needle and thread, whereby the said beads are fixed to the fabric to be embroidered.

Figure 1 is a vertical longitudinal sectional view of a machine embracing my said invention. Fig. Zis a rear-most view,on an enlarged scale, of oneportion of theapparatus. Fig.3 is a vertical sectional view taken in substantially the same plane as Fig. 1, but, like Fig.

2, on an enlarged scale. Fig. 4 is .a detailed view, on a still larger scale, of one part of the feeding devices.

The apparatus comprised in my said invention, and hereinafter more particularly defined, is designed to be used upon or in connection with a common embroidering-machine,in which the movement of the tambour-frame or its equivalent is regulated by a pantogra h, and in which a double-pointed needle carrying the thread is transferred from side to side of the fabric by griping devices, which pass back and forth to perform the embroidered pattern upon the said fabric.

In the drawings there is the usual duplicition ofthe embroidering-frames or othercquivalents, A, and the usual duplication of the pairs of opposing gripingdevices, B, which operate in connection with the usual thread and doublepoiuted needles a. The construction of these devices and the means by which they are actuated are well known and understoodin the art, and need not be further described.

The apparatus for transferring the beads, or, as they are technically termed, the pearls, is placed in conjunction with one of the griping devices of each of the pairs of griping devices aforesaid, it being-only required that the embroidery be placed upon one side of the fabric.

The construction of the feeding apparatus is as follows:

Placed in a position parallel with that of the tambour-frame A, is a rock-shaft, 0, upon one end of which is applied a coiled spring, b, in

such wise as to tend to axially turn the shaft backward, as indicated bythe arrow in Fig. 3. Projecting downward from the sa d shaft are two arms, 1).

Immediately below the shaft is the adjacent griping device B, which operates in actuating the needlcashereinbetoreexplained,and which griping device is placed upon the usual carriagc, moved at intervals inward to and away from the fabric on the tambourframe A. EX- tending upward from the base of this griping device, or, in other words, from the carriage thereof, are two posts, F, upon the upper end of each of which is formedan incline, 0. These posts are arranged one under each of the arms 1) of the rock-shaft C, so that when the posts are moved inward toward the fabric by the corresponding movement of the gripingdevices B the inclined upper parts, 0, of the said posts, striking upon the arms 1), will force the said arms I) forward and upward, thereby rocking the shaft 0 forward and upward, the springs b insuring the backward or return movement of the rock-shaft 0 when the posts F are brought back to their original position by the reverse or backward movement. of the griping devices B.

Atfixed to the rock-shaft O are one or more bosses, G, to each of which is attached a detachable downwardly projecting stem, H, which gradually tapers toward itslower end and terminatesin avery thin butstrongcutved tongue,f. This stem H is so proportioned that the beads or pearls may be readily slipped thereon, and the tonguefis relatively of so small a diameter that when the beads or pearls are situated thereon sufticient space is left within the cent al orifices ot' the said beadsor pearls to permit the needle to pass through the same, notwithstai'iding the fact that said space or central orifice of 'each head or pearl is also occupied by the curved tongue of the stem aforesaid. Also attached to each boss G, and preferably made detachable therefrom by nuts g,are two curved springs, l and J, the lower end of each of which is notched, as shown at a, the curvature at the lower end ofthe spring J being such as to bring the said end somewhat higher than the corresponding end of the spring I. The notched portion of each of the said springs passes astride of the adjacent portion of the lower extremity of the stem H, as indicated in Fig. 4. The needle a passes underneath the lower end of the spring J and through the notch aof the spring I. The said springs are stiffened ,by rigid braces m and n, which extend downward and forward movement of the rock-shaft G the said arm K, at a certain period of the said upward and forward stroke, will sttike the bar L and pull back the spring J with-reference to the spring I and the stem H, to permit the beads or pearls upon the main portion of the said stem to descend upon the curved lower end thereof.

In the operation of the apparatus the needle, being actuated, as hereinbefore stated, in the usual manner, in itsinward movement toward the fabric or tamhour-fra me passes immediately under the lower extremity of the spring J, and also immediately under the thin curved lower end of the stem H; and inasmuch as the lowermost head or pearl upon the said stein H, depending from the said curved lower end of the stem, springs to a substantially vertical position with, as hereinbet'ore explained, a considerable portion of its interior unoccupied by the stem, the needle passes into this unoccupied portion of the interior of thebead or pearl, and carries withit the thread attached to the needle in the usual manner, the movement of the needle being thus continued to and through the fabric, whereuponit is caught by the griping devices B at the opposite side to form the stick in the usual manner. This forward andinward movementofthe needle is of course caused by a corresponding movement of the griping devices B, by which it is gliped and held, and this inward movement of said devices B carries with the said devices the posts F and their inclined upper parts, 0, which, striking the arms D, as helvinbefore explained, spring the stem H and the springs I and J inward and upward by the expansion movement of the rock-shaft U, to which they are attached, until the arm K, having been arrested by the fixed bar L, causes the spring J to be drawn back, so far as concerns its relations with the stem H, thereby permitting the lowermostot' the beads or pearls explained, so that the next movement in the same direction of the ncedlea will pass through the said head or pearl upon the stitch next formed upon the fabric, and so on, all infinitum, with each movement in said direction of the needle a. g

It is to be understood that any desired number of the feeding apparatus just hereinbefore explained may be placed upon the shaft O, to indicate which I have placed a second boss,- G, and attached spring J in Fig. 2. As concerns the lower and upper series of griping devices, there must of course be placed in suitable relation with one of the devices of said pairthe rock-shaft 0, provided with the requisite or desired number of the feeding apparatus. In other words, to each pair of opposing griping devices there must be one of the rock- 'shafts G, and in connection with one rock-shaft 0 there may be used any desired number of needle'gripping devices, each provided with a feeding apparatus in the manner hereinbefore fully set forth.

What I claim as my invention is 1. A bead-feeding device for embroideringmachines, having as its essential elements a stem, H, having a thin curved lower extremity, f, opposing springs I J, for controlling the movements of the beads upon the said stem, and means, substantially as described, for giving simultaneous movement to the stem H and springs I J in unison with the movements of the stitch-forming mechanism of the embroidering-machine, all substantially as and for the purpose herein set forth.

2. The combination, in a bead-feeding apparatusfor embroidering-machines, otthe rockshaft 0, stem H, having a thin curved lower extremity, opposing springs I J, arm K, and

a bar or stop, L, the whole combined to provide for the feeding of the beads to the curved lower end of the stem H in unison with the reciprocating movement of the needle of an embroidering-machin e, all substantially as and for the purpose herein set forth.

3. The combination, with the double-pointed needle, and ofthe griping device of an embroidering-machine, of the posts F, having an incline, c, the rock-shaft (3, having arms 1), the stem H, having the thin curved lower extremity, f, the opposing springs I J, and a boss, G, or equivalent means for connecting the stem and springs to the rock-shaft,the whole arranged for joint use and operation, substantially as and for the purpose herein set forth.
